    Can you help me with this...many thanks

  • grayanne Feb 10, 2008

    hi c-dog. i can't find a reset feature in the menu the only reset button i can find is the reset button on picture adjust section. i tried unpluging the wall outlet but still the problem exist, actually i can only view the menus while im turning off the lights and trying to sit very close on the tv, that way i can see a little shadows of the words, basically a black pop-up onscreen on display still showing when pressing any feature button on the remote.

  • grayanne Feb 11, 2008

    sorry im not a technician.

    by the way, on the black pop-up onscreen display whenever i press the feature buttons, when i stand close to the tv and turn off the lights i could see some shadowing of the words but very very minimal visibility and its so hard to read

  • grayanne Mar 01, 2008

    i was thinking too that its a convergence problem, because when im turning on the tv there's a green shadowing on the left side, but when you start watching programs you wont see that green shadows.

    can you just tell me how to fix that convergence problem, i really dont know how, or do i need a qualified technician to do that, or i can do it too?

In your customer menu there is a convergence adjustment feature. just follow the instructions on how to do it. It's pretty simple. But if that doesn't do it, then you may have some components shorted or open in the convergence circuit. If so, then you will need a qualified tech to repair it.

I'm not entirely sure, but I think the problem lies in your Convergence OSD PWB. I had to disconnect mine in the attempt to troubleshoot a problem with my TV and the same thing occurred. I would check your connection from your Convergence PWB to your Convergence OSD PWB; especially if you recently recently changed your IC's to fix a color convergence problem. If that checks out ok I would look for possible problems on the Convergence OSD PWB. Good luck!

    Try and see if there is some sort of a reset feature in the menu. Also try to unplug the set from the wall outlet for a few minutes then plug it back in. That resets the microprocessor from being stuck in a loop of some kind.

    When the internal temperature gets high then the photo coupler efficiency decreases. This would sometimes result in the menu display freezing up not being able to see any of the PTV functions. Are you a technician?

When unit is turned on, it defaults to Vid1. My Direct TV Satellite is hooked up to CMP - component input. Is there any way to make the TV default to CMP when it is turned on?


Bring up the menu on your TV. At the bottom of the menu should be the Setup menu. Choose it and press OK on your remote. You will then get another menu and one of the choices will be Preferences. Highlight it and press OK. On the next menu choose Special Features and press OK. The last menu should have a choice titled Initial Channel. Highlight this choice and then using your Left and Right buttons on either side of the OK button you will be able to scroll through all of your channels as well as all of the Inputs that are on the back and front of your TV. Scroll through the choices until you see CMP. Then you can either highlight and choose the Go Back choices at the top left of each menu, or just press the Clear button on your remote until you exit the menu system.

Now when your turn your TV on it should default to CMP. The same menu that you chose CMP through will also allow you to choose the Initial Volume on startup,

Possibly the closed caption feature on this set has been turned on. There is a button on the remote control that says Caption. Press it until you turn the caption off. This will not be on a universal remote, only the original remote. You can also turn this off through the caption section on your on-screen menu.
